|Title||X-ray emission from the A0p star IQvirgulAur|
|Author||Prof J rgen Schmitt|
|Description||We propose to use XMM-Newton to obtain the first high-resolution X-ray spectrum of the peculiar magnetic A-type star IQvirgulAur. From previous X-ray observations IQvirgulAur is known as a strong, but very soft X-ray source. In addition to the HAeBe star HDvirgul163296, IQvirgulAur is a very good candidate for an A-type star with intrinsic X-ray emission. The XMM-Newton RGS spectrum will strongly constrain the location of the X-ray emission site from a measurement or upper limit to the strength of the OVII f-r line ratio, the overall RGS spectrum will determine the elemental abundances, which may be far from solar, and finally, the phase coverage of the EPIC data will be sufficient to search for a rotational modulation of IQvirgulAur.s X-ray flux.|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
